Here we first list some of the preliminary set of basic notations that we will use throughout the text, followed by a brief introduction to the tools and concepts needed for the formal definition of a semihypergroup (referred to as `semiconvo' in [1]}). Finally, we list some of the well-known natural examples of a semihypergroup [2]}, [1]}, [4]}. All the topologies throughout this text are assumed to be Hausdorff, unless otherwise specified.
